The equation formula is y - y1 = m(x-x1)
Using the first point for x1, y1:
Y +13 = m(x-15)
M is the slope which is the change in y over the change in x:
M = -11–13 / 16-15 = 2/1 = 2
The equation becomes y +13 =2(x+15)
The answer is:
He incorrectly wrote the slope in his equation. He should have written y+13=2(x−15).
Answer:
Step-by-step explanation:
Given a large enough sample size the probability is 100%
If the question is "What is the probability of catching 3 tennis balls in three tosses in mid air. Sample size is 3
0.74³ = 0.405224 or about 41%
All transportation (bus, cab, train) are all similarly likely to be selected, and 1 of them must be selected at morning and evening, so we get: P (bus) = P (cab) = P (train) = 1/3. We also have P(no cab in evening) = P(no cab at morning) = 2/3
Now, P(using cab exactly once) = P(cab at morning and no cab in the evening) + P(no cab at morning and cab in the evening)
= P(cab, no cab) + P(no cab, cab)
= 1/3 * 2/3 + 2/3 * 1/3
= 2/9 + 2/9
= 4/9
Probability that Elizabeth uses a cab only once is 4/9.
Mark spent a total of 80 minutes or 1 hour and 20 minutes traveling to and from work.
45 minutes + 35 minutes = 80 minutes
There are 60 minutes per hour, so their would 1 hour and 20 minutes.
Step-by-step explanation:
In ️ BEA and ️ CED
EB=EC ----given
angle ABE= angle DCE --------- given
angle DEB= angle DCE -------vertically opposite angles are equal
Hence, ️ BEA is congruent to ️ CED
